好多离合器液压操纵系统内放空气比较困难,这是经常听到的,杂志上也介绍过一些方法。我们认为造成难的原因一般是总泵进油困难,空气排不出建立不起压力,(总泵有故障的除外,特别是回油孔被皮碗堵塞)。再加上有的车型连接管的内径大,中途所形成的气段则更难排出。如果把油从分泵注入,那末空气就很客易排出了,同样大内径管子由于从分泵注油流 A lot of clutch hydraulic control system to put the air more difficult, it is often heard, the magazine also introduced some methods. In our opinion, the cause of difficulty is that it is difficult for the master cylinder to enter the oil. The pressure of the air can not be built up, except for the failure of the master cylinder. In particular, the oil return hole is blocked by a cup. Coupled with some models of the inner diameter of the connecting pipe, the gas section formed halfway is more difficult to discharge. If the oil from the sub-pump injection, then the air is very easy to discharge, the same large diameter pipe due to the sub-pump oil flow
